Vans Old Skool Core Classics fits in the same number as Air Force 1, Air Jordan 1, Air Max 90, adidas Superstar, Nike Dunk Low, and the standard Vans Old Skool — essentially the entire AF1/AJ1/AM90 cluster. At offset +0.165, Old Skool Core Classics bridges the AF1 cluster (0.000) and the AJ1 cluster (+0.217), rounding to "same" as both. Based on 178 owner-reported pairs in the Feetlot database, the premium leather Core Classics construction fits the same number as the canvas Old Skool — the different upper material does not require a size change. If unsure: order true to size. Only YEEZY Boost 350 V2 runs half a size larger in number.

- Carrying YEEZY 350 V2 sizing over directly. YEEZY 350 V2 runs about half a size larger in number. If you wear YEEZY 350 in 10, take Old Skool Core Classics in 9.5.
- Sizing differently than AF1 or AJ1. Old Skool Core Classics, AF1, and AJ1 all round to the same size. Same number across all three.
How Feetlot Computes These Numbers
Every Vans Old Skool Core Classics sizing recommendation on Feetlot is the output of a global offset model fit to over 100,000 owner-reported shoe records.
